Abstract:  THE 45-ACRE LEMBERGER TRANSPORT AND RECYCLING (LTR)) SITE IS A FORMER LAND DISPOSAL FACILITY IN MANITOWOC COUNTY, WISCONSIN. THE SITE IS LOCATED WITHIN ONE-QUARTER MILE OF THE 45-ACRE LEMBERGER LANDFILL (LL) SITE. LAND USE IN THE AREA IS PREDOMINANTLY AGRICULTURAL, WITH FOUR RESIDENCES WITHIN 1,000 FEET OF THE SITE. GROUND WATER AS WELL AS THE BRANCH RIVER, LOCATED LESS THAN 1 MILE WEST OF BOTH SITES, ARE USED AS SOURCES OF DRINKING WATER. FROM 1970 TO 1976, THE LTR SITE RECEIVED INDUSTRIAL WASTE AND A VARIETY OF LIQUIDS, SLUDGE, AND SLURRIES, WHICH WERE DEPOSITED IN UNLINED TRENCHES. FROM 1940 TO 1969, FRANKLIN TOWNSHIP USED 21 ACRES OF THE LL SITE AS AN OPEN DUMP. AFTER 1970, THE STATE LICENSED THE LANDFILL TO RECEIVE ONLY MUNICIPAL WASTE AND POWER PLANT FLY ASH AND BOTTOM ASH. ALL INDUSTRIAL WASTE WAS DIVERTED TO THE NEARBY LTR SITE. REPORTS OF CONTAMINATED MATERIAL SEEPING ONTO LOCAL PROPERTIES PROMPTED STATE INVESTIGATIONS THAT REVEALED VOCS IN RESIDENTIAL WELLS IN EXCESS OF STATE STANDARDS. AFFECTED RESIDENCES RECEIVED DEEPER REPLACEMENT WELLS THAT HAVE NOT SHOWN CONTAMINATION. BECAUSE OF THE SIMILARITY OF CONTAMINATION AND PROXIMITY OF THE SITES, THE LTR AND LL SITES WILL BE ADDRESSED CONCURRENTLY. THIS RECORD OF DECISION (ROD) PROVIDES A FINAL REMEDY FOR GROUND WATER CONTAMINATION AT BOTH THE LTR AND LL SITES, AS THE FIRST OPERABLE UNIT (OU1). A FUTURE ROD WILL ADDRESS THE LANDFILL CONTENTS AT THE LTR SITE, AS OU2. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE GROUND WATER ARE VOCS INCLUDING PCE, TCE, TOLUENE, AND XYLENES; OTHER ORGANICS INCLUDING PCBS AND PESTICIDES; AND METALS INCLUDING ARSENIC, CHROMIUM, AND LEAD.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES BUILDING AN ONSITE TREATMENT FACILITY AT THE LL SITE AND TREATING CONTAMINATED GROUND WATER FROM BOTH SITES USING ELECTROCHEMICAL PRECIPITATION TO REMOVE INORGANIC CONTAMINANTS AND GRANULAR ACTIVATED CARBON TO REMOVE ORGANIC CONTAMINANTS, UNLESS TREATABILITY STUDIES DEEM ANOTHER TECHNOLOGY TO BE MORE EFFECTIVE; BLENDING WATER EXTRACTED FROM THE SLURRY WALL TO BE CONSTRUCTED AT THE LL SITE WITH GROUND WATER EXTRACTED FOR REMEDIATION, AND TREATING IT ONSITE AT THE TREATMENT FACILITY; TEMPORARILY STORING RESIDUAL SLUDGE ONSITE, THEN TREATING AND DISPOSING OF THE RESIDUAL SLUDGE AS PART OF THE FUTURE LTR SOURCE CONTROL REMEDY OR TREATING AND DISPOSING THE SLUDGE OFFSITE AT A RCRA LANDFILL ACCORDING TO FEDERAL AND STATE REGULATIONS; RECYCLING SPENT CARBON, IF POSSIBLE; DISCHARGING THE TREATED EFFLUENT INTO THE BRANCH RIVER; PROVIDING AN ALTERNATE WATER SUPPLY TO RESIDENTS WHOSE WATER SUPPLY IS DISRUPTED DUE TO THE OPERATION OF THE EXTRACTION SYSTEM; INVESTIGATING AND MITIGATING ANY AFFECTED WETLANDS; MONITORING GROUND WATER; AND POSSIBLY IMPLEMENTING INSTITUTIONAL CONTROLS INCLUDING DEED AND GROUND WATER USE RESTRICTIONS, AND CONSTRUCTING A SECURITY FENCE AROUND THE TREATMENT FACILITY TO LIMIT GENERAL ACCESSIBILITY TO THE FACILITY AND THE POTENTIAL FOR PUBLIC EXPOSURE. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $19,200,000, WHICH INCLUDES THE SOURCE CONTROL REMEDY FOR THE LL SITE AND AN ANNUAL O&M COST OF $731,000 FOR YEARS 0-1 AND $596,000 FOR YEARS 2-30.

PERFORMANCE STANDARDS OR GOALS; CHEMICAL-SPECIFIC GROUND WATER CLEAN-UP GOALS ARE BASED ON THE MOST STRINGENT OF STATE STANDARDS, SDWA MCLS, AND RISK-BASED LEVELS, AND INCLUDE PCE 0.1 UG/L (STATE), TCE 0.18 UG/L (STATE), TOLUENE 68.6 UG/L (STATE), XYLENES 124 UG/L (STATE), ARSENIC 5 UG/L (STATE), CHROMIUM 5 UG/L (STATE), LEAD 5 UG/L (STATE), AND PCBS 0.5 UG/L (PMCL).
 
Remedy:  THE SELECTED REMEDIAL ACTION IS THE FIRST OPERABLE UNIT AT THE SITE. OPERABLE UNITS ARE DISCRETE ACTIONS THAT COMPRISE INCREMENTAL STEPS TOWARD THE FINAL REMEDY. A SECOND AND FINAL OPERABLE UNIT WILL ADDRESS THE LANDFILL CONTENTS. THE SELECTED REMEDY ADDRESSES THE GREATEST RISKS POSED BY CONDITIONS AT THE SITE, EXPOSURE BY INGESTION OR DIRECT CONTACT WITH CONTAMINANTS IN THE GROUND WATER. THE REMEDY WILL ACHIEVE SUBSTANTIAL RISK REDUCTION THROUGH EXTRACTION AND TREATMENT OF THE CONTAMINATED GROUND WATER AT THE SITE.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY FOR THIS FIRST OPERABLE UNIT INCLUDE;
* INSTALLATION OF GROUNDWATER EXTRACTION WELLS;
* EXTRACTION OF CONTAMINATED GROUND WATER TO ACTIVELY RESTORE THE AQUIFER TO FEDERAL AND STATE OF WISCONSIN GROUNDWATER QUALITY STANDARDS;
* CONSTRUCTION OF A GROUND WATER TREATMENT SYSTEM;
* MONITORING OF GROUND WATER TO ENSURE EFFECTIVENESS OF THE REMEDIAL ACTION.
